There's a thing called Game Designing.
You don't need to know how to make a game to be able to design it.
Pen and paper is the best game designing program. Common sense on what can and can't be done is recommended.
Programmers are the blue collar workers of game industry (though their average wage is higher compared to designers), while designers are the architects.
Smaller game studios have more split duties like: designer/programmers, artist/designers etc.
Knowledge in programming is a huge pro though so I recommend studying a variety of languages. Facebook, Iphone and other casual platforms are on the rise so studying programming languages suitable for them could be a smart choice careerwise.
